Quality Control
We follow the highest ISO9001 standards and have developed a complete quality control system to test the quality and performance of our cold chain packaging, such as the testing of phase change materials in our CNAS laboratory. We also promise to provide customers with full test reports.
Our Customer-oriented Quality Control System
Our QC system includes purchase management , in-process inspections, laboratory evaluations, and third-party assessments. Additionally, we integrate customer feedback into our system, enabling us to understand client needs promptly and drive continuous improvement of our cold chain package.
Raw Material Testing
We conduct component analysis and performance testing on all incoming materials, ensuring they fully meet standards before they are accepted into our inventory.
PCM Testing
In our CNAS laboratory, we adhere to the GB/T 34399-2017 standard to test the phase transition point, viscosity, electrical conductivity, pH value, and other properties of phase change materials, ensuring superior insulation performance.
Durability Testing
After repeated tests, our insulation bags still maintain complete insulation performance after 100 cycles of use, and the damage rate is less than 1%.
Insulation Performance Testing
Our thermal insulation bags can keep the internal temperature below 5℃ for up to 12 hours at room temperature (25℃), which has excellent thermal insulation effect.
Environmental Impact Assessment
After experimental evaluation, our insulation bags can reduce carbon emissions by about 18% over the entire life cycle compared to traditional disposable insulation bags. They are an ideal choice for your sustainable development.
Shipping Inspection
Before loading, our inspectors will check again to ensure that the order meets customer requirements and is shipped intact.
Authoritative Report
Our commitment to quality is verified by authoritative institutions. In addition to the following third-party test reports, we provide customers with other reports such as oral toxicity tests to enhance your confidence in our temperature-controlled packaging solutions.
